Objective The purpose of this study is to determine whether a Transversus Abdominis Plane (TAP) block can reduce donor site morbidity among pediatric patients undergoing iliac crest bone grafting for repair of their alveolar cleft. Design This retrospective cohort study was carried out at the Division of Dentistry at the Montreal Children's Hospital. Medical charts of patients who underwent alveolar cleft bone grafting between January 2011 and January 2021 were reviewed and they were divided into two groups, intraoperative TAP block and intraoperative local anesthesia infiltration (control group). The outcomes measured were patients’ post-operative pain at the donor site, in-hospital narcotics requirements and length of stay. Results A total of 66 patients were included. There were no significant differences in pain scale among the TAP group and control group [1.9 (SD 2.5) and 1.3 (SD 2.1), respectively ( p = 0.23)]. The mean length of stay for both groups was 1 day. Interestingly, there was a significant higher proportion of patients who required in-hospital opioids (morphine) in the TAP block group when compared to the control group ( p = 0.03). Conclusions The results of our study suggest there may be no role for a TAP block in reducing pain and improving opioid stewardship.

Background: Patients undergoing periacetabular osteotomy (PAO) may experience significant postoperative pain due to the extensive approach and multiple osteotomies. The aim of this study was to assess the efficacy of the transversus abdominis plane (TAP) block on reducing opioid consumption and improving clinical outcome in PAO patients. Patients and Methods: We conducted a two-group randomized-controlled trial in 42 consecutive patients undergoing a PAO for symptomatic developmental dysplasia of the hip (DDH). The study group received an ultrasound-guided TAP block with 20 mL of 0.75% ropivacaine prior to surgery. The control group did not receive a TAP block. All patients received a multimodal analgesia with nonsteroidal anti-inflammatory drugs (NSAID) (etoricoxib and metamizole) and an intravenous patient-controlled analgesia (PCA) with piritramide (1.5 mg bolus, 10 min lockout-time). The primary endpoint was opioid consumption within 48 h after surgery. Secondary endpoints were pain scores, assessment of postoperative nausea and vomiting (PONV), measurement of the quality of recovery using patient-reported outcome measure and length of hospital stay. Forty-one patients (n = 21 TAP block group, n = 20 control group) completed the study, per protocol. One patient was lost to follow-up. Thirty-three were women (88.5%) and eight men (19.5%). The mean age at the time of surgery was 28 years (18–43, SD ± 7.4). All TAP blocks were performed by an experienced senior anaesthesiologist and all operations were performed by a single, high volume surgeon. Results: The opioid consumption in the TAP block group was significantly lower compared to the control group at 6 (3 mg ± 2.8 vs. 10.8 mg ± 5.6, p < 0.0001), 24 (18.4 ± 16.2 vs. 30.8 ± 16.4, p = 0.01) and 48 h (29.1 mg ± 30.7 vs. 54.7 ± 29.6, p = 0.04) after surgery. Pain scores were significantly reduced in the TAP block group at 24 h after surgery. There were no other differences in secondary outcome parameters. No perioperative complication occurred in either group. Conclusion: Ultrasound-guided TAP block significantly reduces the perioperative opioid consumption in patients undergoing PAO.

Introduction: Transversus abdominis plane (TAP) block is a regional anesthesia that involves the infiltration of local anesthetic in between the internal oblique and transversus abdominis muscle plane. This block provides post-operative analgesia and reduces the requirement of opioids consumption. Objective: To assess the effectiveness of TAP block in providing postoperative analgesia in women undergoing caesarean section. Methodology: This was a hospital based prospective, comparative, cross sectional study conducted in 70 patients from 17th September 2018 to 17th February 2019 undergoing caesarean section under spinal anesthesia. Patients were divided into two groups. Group A patients received TAP block with 0.5% Ropivacaine versus Group B patients received injection paracetamol 1gm intravenous every 8 hourly as a standard and routine analgesic. At the end of the surgery, TAP block was performed by anesthesiologist and assessment of postoperative pain using a visual analogue pain score at every 1 hour, 3 hour, 6 hour, 12 hour and 24 hour by trained staffs at postoperative ward. Then, depending upon the severity of the pain injection fentanyl 1mcg/kg intravenous was given as rescue analgesia. Short assessment of patient satisfaction (SAPS) score was also assessed 24 hours postoperatively. Results: Compared to control group, in women who received TAP block, there was statistically significant reduction in pain at 3 hr, 6 hr, 24 hrs. However at 12 hrs there was no significant difference in the pain score. The cumulative fentanyl requirement was also significantly less in the TAP block group at all the time points.  Conclusion: The TAP block provided highly effective postoperative analgesia following caesarean section and reduces the fentanyl requirement in the first 24 hour.

Background: The ultrasound guided transversus abdominis plane (TAP) block which provides effective analgesia after lower abdominal surgeries including caesarean section. It is a simple and reliable technique. In this prospective, randomized double-blind study, we determined the efficacy of TAP block using 0.25% Bupivacaine and 0.9N Saline with respect to VAS for pain, postoperative Tramadol consumption and post-operative ondansetron usage.Methods: This study was conducted on 100 adult patients of ASA physical status I and II in the   age group of 18 to 40 years undergoing elective lower segment cesarean section under spinal anaesthesia. Study group received TAP block with 0.25% Bupivacaine and control group received 10 ml of 0.9N saline on each side. Patients were analyzed for postoperative pain by pain score (at rest, on movement, on cough) using VAS was recorded at 0, ½, 1, 2, 4, 6, 12 and 24 hours postoperatively. Need for rescue analgesia was assessed by time to first dose of Tramadol requirement and total dose of Tramadol over 24 hours of postoperative period. Ondansetron (4 mg i.v.) was administered whenever nausea score was more than 2 or the patient vomited. All the data was noted using uniform performs.Results: Patients received TAP block with 0.25% Bupivacaine had better pain scores at first hour of postoperative period during rest, cough and movement which was statistically significant (p<0.0010) in comparison to group B. There was a statistically significant difference (p <0.001) in the requirement of total dose of Tramadol as a rescue analgesia in patients who received transversus abdominis block with 0.25% Bupivacaine (138.77 mg) in comparison with other group(240 mg).The mean time to first request for Tramadol was significantly longer in group A (5.8 hrs)  in comparison to group B (1.93 hrs) with p value <0.001. Patients received TAP block with 0.9N saline needed more dose of Ondansetron, however, the difference was not statistically significant (p >0.001).Conclusions: TAP block using ultrasound provides substantial reduction in Tramadol consumption, time to first dose of rescue tramadol when compared with control group. This study reinforces the recommendation for TAP as a part of multimodal post-operative analgesic regimen.

INTRODUCTION Reducing exogenously administered opioids in the post-operative period is associated with early return of bowel function and decreased post-operative complication rates. We evaluated the effectiveness of a surgeon-delivered open transversus abdominis plane (TAP) block as a method to reduce post-operative opioid requirements, sedation and inpatient stay. METHODS The patient cohort was identified from those who had undergone a right hemicolectomy for colonic cancer. Patients received either an open TAP block and post-operative patient controlled anaesthesia (PCA) (n=20) or were part of a control group who received subcutaneous local anaesthetic infiltration and PCA (n=16). RESULTS PCA morphine use was reduced within the first 24 hours post-operatively in the TAP block group compared with controls (42.1mg vs 72.3mg, p=0.002). Sedation was also reduced significantly in the early post-operative period (p<0.04). There was a non-significant trend towards reduced length of stay in the intervention group (8.2 vs 8.73 days). There were no recorded complications attributable to the open TAP block. CONCLUSIONS Open TAP blocks are safe and reduce post-operative opioid requirements and sedation after right hemicolectomies. They should be considered as part of a multimodal enhanced recovery approach to patients undergoing abdominal surgery via a transverse incision.

Introduction: The TAP block is a regional anesthetic technique, which blocks neural afferents between T6 and L1, which provide anterior abdominal walls and therefore help to alleviate postoperative pain. Aim: The aim is to compare the efficacy of preoperative single low dose of intravenous MgSO4 versus intravenous dexamethasone as adjuvants to ultrasound guided TAP block for prolongation of postcesaren analgesia. Materials and Methods: A total 60 pregnant females were selected undergoing elective caesarean sections under general anesthesia with ultrasound-guided transversus abdominis plane (TAP) block done at the end of surgery. Patients were randomly and equally allocated into three groups of 20 patients each. The first group of patients were classified as magnesium sulphate group (M)who received 50 mg/Kg IV, the second group of patients were classified as dexamethasone group (D) who received 2 mg IV and the third group was classified as the placebo group (C) who received IV saline. Results: Comparison of the VAS at 6 and 12 hours postoperatively showed statistically significantly lower values in group (M) and group (D) compared to group (C) and also group (M) was significantly lower than group (D) as well. The time interval until first rescue analgesia (Nalbuphine) needed by the patients (VAS ≥ 50) was significantly longer in group (M) compared to group (D) and group (C) consecutively. Additionally, it was significantly longer in group (D) than in the control group(C). The total dose of rescue analgesia consumed during the first 24 hours postoperatively was significantly lower in groups (M) than in group (D) and both groups showed lesser doses compared to group (C) Conclusion: We concluded that both MgSO4 and dexamethasone could prolong the postoperative duration and analgesic efficiency provided by the TAP block in cesarean sections. This further reduced the demands for postoperative rescue analgesia, with MgSO4 found to be more efficient than IV dexamethasone. Clinical Trial Registration Number: NCT04223128

Abstract Background: Enhanced recovery protocols optimize pain control via multimodal approaches that include transversus abdominis plane (TAP) block. The aim of this study was to evaluate the effect of preoperative vs postoperative nonliposomal bupivacaine TAP block on postoperative narcotic use after colorectal surgery.Methods: A retrospective cohort study comparing postoperative narcotic use in patients who received preoperative (n = 240) vs postoperative (n = 22) nonliposomal TAP blocks. The study was conducted in a single tertiary care institution and included patients who underwent colorectal resections between August 2018 and January 2020. The study measured narcotics use in the postoperative and follow-up periods, operative details, length of stay, reoperation, and readmission rates.Results: Patients who received postoperative nonliposomal bupivacaine TAP blocks were less likely to require postoperative patient-controlled analgesia (PCA) (59.1% vs 83.3%; p = 0.012) and opioid medications on discharge (6.4% vs 16.9%; p = 0.004) relative to patients who received preoperative TAP. When needed, a significantly smaller amount of opioid was prescribed to the postoperative group (84.5 vs 32.0 mg, p = 0.047). No significant differences were noted in the duration of postoperative PCA use, amount of oral narcotic use, and length of stay.Conclusions: Nonliposomal bupivacaine TAP block administered postoperatively was associated with significantly lower need for postoperative PCA and discharge narcotics. Given the overall short length of stay for the 2 groups, further study is needed to justify the additional cost of liposomal bupivacaine TAP blocks for patients undergoing colorectal resections.

BACKGROUND: Patients undergoing bariatric surgery present unique analgesic challenges, including poorly controlled pain, increased prevalence of obstructive sleep apnea, and opioid-induced respiratory depression. The transversus abdominis plane (TAP) has been demonstrated to be a safe and effective component of multimodal analgesia for a variety of abdominal surgeries. OBJECTIVE: To determine the benefits of the TAP block on postoperative analgesia and recovery in patients undergoing bariatric surgery. STUDY DESIGN: Systematic review and meta-analysis of randomized controlled trials (RCTs) and non-randomized studies. METHODS: We conducted a comprehensive search of MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) databases from inception to April 2020 for studies using TAP block in bariatric surgeries and reporting postoperative pain, opioid consumption, and recovery-related outcomes. Primary outcomes included postoperative pain scores, opioid consumption, and recovery-related outcomes (e.g., length of stay, time to ambulation). Outcomes were pooled using random effects model and reported as relative risks (RR) or mean differences (MD) with 95% confidence intervals (CI). RESULTS: Twenty-one studies (15 RCTs [n = 1410] and 6 nonrandomized studies [n = 1959]) were included. Among RCTs, the TAP block group required fewer opioid rescues (RR 0.28; 95% CI 0.18 to 0.42, P < 0.001) (moderate quality); reduced total opioid use over 24 hours (MD –8.33; 95% CI –14.78 to –1.89, P = 0.01); decreased time to ambulation (MD –1.12 hours; 95% CI –1.50 to –0.73, P < 0.001) (high quality); and had significantly lower pain scores at 6 hours (MD –1.52; 95% CI –1.90 to –1.13, P < 0.01) and 12 hours (MD –0.95; 95% CI –1.34 to –0.56, P < 0.001) on a 0-10 pain scale (moderate quality). No difference was observed for nausea and vomiting, or hospital length of stay. Meta-analyzed outcomes from observational studies supported these results, suggesting decreased postoperative pain and opioid consumption. LIMITATIONS: Studies varied with respect to type of surgery and components of comparator multimodal analgesia, likely contributing to heterogeneity. Subgroup analyses by type of comparator group were conducted to address these differences. We were unable to extract data from all trials included due to variability in outcomes reporting, such as non-opioid drugs for postoperative pain management or invalid dosages. Pain-related outcomes may be affected by operative differences leading to variation in visceral pain. Observational studies have their inherent limitations, such as confounding due to lack of participant randomization and intervention blinding, potentially affecting subjective outcomes, such as pain scores, as well as provider-dependent outcomes, such as hospital length of stay. Lastly, there was significant variation of TAP block technique across all studies. CONCLUSION: TAP block is an effective, safe modality that can be performed under anesthesia. It decreases pain, opioid use, and time to ambulation after bariatric surgeries and should be considered in multimodal analgesia for enhanced recovery in this high-risk surgical population.

BackgroundTreatment of ovarian cancer often requires extensive surgical resection. The transversus abdominis plane (TAP) block has been utilized in benign gynecologic surgery to decrease post-operative pain and opioid use. We hypothesized that TAP blocks would decrease total opioid use in the first 24 hours and decrease length of stay following staging and cytoreductive surgery for ovarian cancer compared with either no local anesthetic or local wound infiltration alone.MethodsAll patients undergoing surgery for ovarian cancer from November 2016 to June 2017 were included in this retrospective cohort study. Median opioid use at 24, 48, and 72 hours post-operatively, as well as length of stay, were assessed. Multivariate median regression analysis was performed to adjust for potential confounders: post-operative non-steroidal anti-inflammatory drug (NSAID) usage, pre-operative opioid consumption, and extent of cytoreductive surgery. Length of stay was compared using Cox regression analysis.ResultsOne-hundred-and-twenty patients were included in the analysis. Eighty-two patients had a TAP block, while 38 did not. After adjusting for potential confounders there was no difference in median 24 hours opioid consumption (p=0.29) or length of stay (HR 0.95, p=0.78) between patients receiving TAP block compared with those without. After adjusting for potential confounders, patients receiving scheduled NSAIDs had a 2.6-fold greater likelihood of being discharged (p<0.0005) and a significant reduction in median opioid use at 24 hours (23.5 vs 14.5 mg) (p=0.017) compared with those patients without NSAIDs.DiscussionPost-operative administration of NSAIDs, but not TAP block, was associated with a decrease in post-operative opioid use and length of stay following surgery for ovarian cancer. Further investigation into alternative regional anesthetics for Enhanced Recovery after Surgery (ERAS) protocols is warranted.
